Seahawks receiver Percy Harvin tweeted Tuesday that he will need to have surgery on his injured hip.

Harvin a receiver who was the team’s key offensive offseason acquisition was in New York getting a second opinion on his ailing hip while the Seahawks were practicing at the Virginia Mason Athletic Center.

After the practice coach Pete Carroll said the team had nothing new to report on Harvin who has been on the Physically Unable to Perform list since the team opened training camp on Thursday.

But later in the day Harvin tweeted “when everything is goin good sometimes life throw u a curve ball... sorry to half to report that my injury will require surgery...”

Later Harvin added in another tweet: “Nobody was more anxious and excited about season then....but I will be back strong as ever..i appreciate all the love and prayers 12th man.”

Carroll refuted after the practice reports that the Seahawks team doctors had made an earlier recommendation that Harvin did not need surgery leading to Harvin seeking a second opinion.

“We are still gathering information’’ Carroll said. “That’s not right because we haven’t made a conclusion a conclusive statement about that yet. We are trying to wait it out and make sure we take all the time that’s available and all of the information so whatever those reports were they weren’t correct.’’

Carroll said that ultimately the final decision on whether Harvin will have surgery will be Harvin’s.

“Eventually he has to say ‘Yeah I’m getting surgery or not.’ He has to OK that. But that’s all going to be with the information from the doctors they are all working it out now and trying to get all the information. There is a lot of background work that we are doing here too. But it will be doctor’s recommendation and of course the patient always gets the final shot.’’

Seattle traded three picks including its first-rounder in 2013 to Minnesota to get Harvin and then signed him to a six-year $67 million contract that includes $25.5 million guaranteed.

Another of Seattle’s high-priced receivers Sidney Rice was also “off-campus’’ Tuesday the term Carroll likes to uses for players who aren’t in attendance.

Rice in fact was about as off-campus as can be having headed to Switzerland to undergo a procedure on a muscle in his knee.

Carroll said he couldn’t offer a lot more detail but stressed that it was not an indication of a serious injury and simply Rice wanting to get some preventive work done on his knee.

“I’m not going to try to tell you what it is” Carroll said. “This is way beyond my pay scale.”
